摘要/Abstract

摘要： 介绍自主研发的海上浮式风机时域耦合仿真程序的基本原理及其关键技术.该程序利用非稳态叶素-动量理论计算海上浮式风机的气动载荷；利用势流理论和Morison方程计算海上浮式风机的水动力载荷；利用准静态悬链线模型计算锚泊系统的作用；利用Kane动力学方程构建系统的动力学控制方程；利用变桨距和发电机转矩控制器调节海上浮式风机的风能捕获效率.研究开展同类程序的对比验证，结果表明该时域耦合程序能够准确地反映海上浮式风机复杂的耦合动力学特性，为海上浮式风机的耦合动力理论研究和数值程序开发提供一定的参考依据.

Abstract: The paper presents the theories of an in-house time-domain simulation code for floating offshore wind turbines. The unsteady blade-element-momentum method with correction methods is applied to calculate aerodynamic loads. Combination of the potential-flow theory and the Morison’s formula are used to calculate hydrodynamic loads. The quasi-static catenary mooring method is implemented to calculate restoring forces from mooring lines. Kane’s dynamic equations are used to establish dynamic governing equation for the system. The generator-torque controller and the full-span rotor-collective blade-pitch controller are used to regulate wind energy tracking. Subsequently, feasibility testing of the code is conducted by a series of code-to-code comparisons, which will benefit researchers in their theoretical study and development of numerical code for floating offshore wind turbines.

Key words: floating offshore wind turbine; numerical code; potential-flow theory; Kane’s dynamic equations; blade-element-momentum
